Trouble Evaluating Open Access ORM

I have been attempting to evaluate Open Access ORM for our development team, but having several errors.

I was attempting to use the wizard to reverse engineer a database. Initially, the base Rad Ajax website that I had created didn't have the correct connection information in the web.config. I found a blog post which helped get those added.

Now, when running the reverse engineering wizard, I get the following error

>>
Object reference not set to an instance of an object.
Please try again after fixing the problem.
NOTE: The settings made so far have been saved to the reversemapping.config file.
<<

This happens even when I only select one simple table. Is there any troubleshooting log file to help solve this problem. The error message doesn't give any hint to the problem.
